Silinder pejal bermassa 8 kg menggelinding tanpa slip pada bidang mendatar. jari2nya 20 cm. pada saat kecepatan linear pusat massa silinder 4 m/s, maka energi kinetik total selinder sebesar ?

Perhatikan gambar . dimana luas penampan M= 10 cm² dan luas penampan N= 200 CM². Jika piston M diberi gaya 4 N. hitunglah gaya yang bekerja pada piston M .

The king wanted to test Abu Nawas’ smartness. So he invited Abu Nawas to the palace. “You want me, your Majesty?” greeted Abu Nawas. “Yes, you have fooled me three times and that’s too much. I want you to leave the country. Otherwise you will have to go to jail” said the king. “If that is what you want, I will do what you said” said Abu Nawas sadly. Then “Remember, from tomorrow you may not step on the ground of this country anymore” the king said seriously. Then Abu nawas left the king palace sadly. The following morning the king ordered his two guards to go to Abu Nawas’ house. The guards were very surprised found Abu Nawas still in his house. He had not left the country yet. Instead leaving the country, Abu Nawas was swimming in small pool in front of his house. “Hey Abu Nawas, why haven’t you left this country yet? The king ordered you not to step on the ground of this country anymore, didn’t he?” said the guards. “Sure he did” answered Abu Nawas calmly. “But look at me! Do I step on the ground of this country? No, I do not step on the ground. I am swimming on the water” continued Abu Nawas. The guards were not able to argue with Abu Nawas so they left Abu Nawas’ house and went back to the palace. The guards reported what they had seen to the king. The king was curious on Abu Nawas’ excuse not to leave the country. Therefore the king ordered his guard to call Abu Nawas to come to the palace. Abu Nawas came to the palace on stilts. The king wondered and said “Abu, I will surely punish you because you haven’t done what I have said. You have not left this country”. The King continued “And now, look at you. You walk on stilts like a child. Are you crazy? The king pretended to be furious. “I remember exactly what you said, Your Majesty” Abu Nawas answered calmly. “This morning I took a bath in the small pool in my house so that I had not to step on the ground. And since yesterday, I have been walking on this stilts. So you see, Your Majesty, I do not step on the ground of this country”. The king was not able to say anything.pertanyaanya : why heve not abu nawas left the country yet ?

1). limit x-9 / √x-3 x⇒9 2). imit x² - x / x²+2x x⇒0 3). limit x-4 / √x² - 16 x⇒4 4). limit √2+x - √2-x / x x⇒0

Answer

FadlyHermaja Ek = 0,5 * (k+1) * m * v^2
= 0,5 * (0,5 + 1) * 8 * 4^2
= 96 joule

adamdhijee Diketahui:
m=8kg
R=20cm⇒R=A⇒ (A=amplitudo)
v=4m/s
Ditanyakan: Ek total=?
Dijawab:
cari kecepatan sudut dahulu:
v=ωA
ω=v/A
ω=4/0,2m
ω=20rad/s

*baru cari Ek tot:
Ek tot=Ek translasi+Ek rotasi
Ek tot=1/2mv²+1/2 Iω²
Ek tot=1/2.8.4²+1/2.(mr²/2).20²
Ek tot=1/2.8.16+1//2.(8.0,2²/2).400
Ek tot=64+8
Ek tot=72 joule
